Determine “G” on Earth
Acceleration Due to Gravity
Experimentally determine “G” (Acceleration due to gravity).
Use a mass set and force scale to determine acceleration due to gravity.
Use the slope formula and your data to calculate acceleration due to gravity.
Use your data and the acceleration formula to calculate acceleration due to gravity.

1. Copy the formula on page 391 and the definition of a Newton. What two values will you use to find acceleration?
2. Remember and use DRY/MIX in setting up your "T"Chart and graph.
The responding variable is Newtons. / The manipulated variable is Grams.
3. Make a “T”Chart. Ask for materials when finished.
4. Use the masses and force scale to produce data for your “T”Chart.
5. Graph your data. The slope of your graph will be acceleration. Slope is rise over run. Slope is Y/X.
6. Use the slope formula to calculate the acceleration due to gravity on Earth. Show your work.
7. Use the equation you copied above to calculate the acceleration due to gravity. Show your work

Energy Questions 1/26
Answer questions 1 through 5 on page 363.

Energy
Work is done when an object moves a distance.
Energy is the ability to do work or cause change.
When energy is transferred to an object work is done.
Moving things have kinetic energy.
Kinetic energy depend on the mass and speed of the thing.
Kinetic energy = 1/2 x Mass x Speed^2
Speed is a greater factor in kinetic energy than mass because it is squared.
This means that a 4kg bowling ball going going 4m/s will have more kinetic energy than an 8kg bowling ball going 2m/s.
This means a 100 lb line-man going 1yds/sec will push back a 200lb line-man going 0.5yds/sec.
Potential energy results from the position or shape of something.
Potential energy related to the height and mass of something is called Gravitational Potential Energy.
Gravitational energy = weight x height
Stretching or compressing an object can produce elastic potential energy.
Mechanical energy results from objects that have both kinetic energy and potential energy.
Mechanical energy = kinetic energy + potential energy.
Objects that fall convert potential energy into kinetic energy.
Energy can be transformed from potential to kinetic and back as in a pendulum.
The law of conservation of energy states that when one form of energy is transformed to another, no energy is destroyed in the process.
Energy just flows from one form to the next.
The kinetic energy of a spinning top is transformed into heat by friction. (floor and air resistance)
